This is a H.263 interoperability bug, OM (probably) does the right thing,
but AG vic (a UCL derivative) has incorrect behavior. We've looked at what
it takes to fix that, and we can put a band-aid on so it won't crash, but
it'll still consume network resources and bandwidth (on the NIC). The long
term solution is to have media on different addresses with preferences --
I'll let Tom Uram expand on that and give a status update.
